About Oxygen Not Included Spaced Out!

Oxygen Not Included: Spaced Out! is an add-on that sends your Duplicants on space missions to new, undiscovered planetoids. You manage multiple colonies at once, move resources between bases and work to build a megacolony that can survive and thrive.

Manage multiple worlds

Juggle the needs of Duplicants across several colonies, switching between planets in real time. Secure rare resources on other worlds to supply your home base.

Rockets and research

Customize modular rockets and explore space using the overhauled Starmap. An expanded Research Tree adds mid-game rocketry options to help your Duplicants compete in the asteroid space-race.

Radiation and nuclear power

Use naturally occurring radioactive elements to power nuclear machines, harness ambient radiation as an energy source and navigate irradiated biomes. Duplicants need lead suits in these areas.

New things to discover

The add-on introduces new critters that may help around the colony, along with new biomes to explore, technologies to research and resources to mine.
